mnoGoSearch supports search query tracking,
which is useful to have statistics about your search engine usage, such as
the most popular queries, the recent queries, the average time spent to
process a search query, and so on.

Query tracking is switched off by default.
To enable tracking, add the trackquery=yes
parameter to the DBAddr
command in your search template.

When performing search, the
front-end uses the qtrack table to
store the following data:

query words

client IP address

the number of documents found

time spent for search (in milliseconds)

the current UNIX timestamp (in seconds from Epoch).

Other search parameters are stored in the qinfo table.

To make a summary of the search queries,
you can execute, for example, this SQL query:

SELECT qwords,count(*),sum(found),avg(found) FROM qtrack GROUP BY qwords;
